| Summary: | 碩士 === 逢甲大學 === 纖維與複合材料學系 === 106 === Noise pollution is accompanied by life. Slight noise can affect concentration and work efficiency. Serious noise can cause direct harm to the human body. In addition, there are more than 1,000 fire accidents in Taiwan each year, of which building materials are often fueling the fire So one of the culprits, it gives building materials flame retardant properties for building safety is extremely important work in order to avoid noise and fire for people's harm, so the purpose of this study is to develop a sound-absorbing flame retardant polyurethane polyurethane building materials, low melting point The main body, composite flame retardant fiber layer, long fiber impact layer, polyurethane sound-absorbing layer to achieve the effect of multi-function.
The best parameters of the multi-functional long fiber reinforced non-woven composite flexible polyurethane cushioning material are as follows: hot bake time 15 minutes, 8 layers of low melting point polyester layer and 1 layer of flame retardant fiber layer, adding long fiber, adding 1.5 % And the fit rate of aluminum foil film, static anti-puncture can reach 1776.40 N (round puncture), falling weight impact absorption energy up to 98 %, sound-absorbing effect in the 500 Hz to 4000 Hz can reach 0.7 or more, LOI value of 33 flame retardant Level, EMI value is above average shading effect.
